Increase default livenessProbe.initialDelaySeconds to 10 minutes

[johngmyers]

Description:

Increases the default for livenessProbe.initialDelaySeconds.

When the on-disk queue grows sufficiently, the agent pod enters a crashloop, with the liveness probe restarting the pod before it finishes startup. The agent pod is thus prevented from uploading any of the data in the queue.

The defaults should be chosen to avoid such problems.
